摘要： A vacuum assisted fetal extraction apparatus and a monitoring device for use in conjunction therewith. The monitoring device includes a circuit including a timer operably coupled with a switch, which may comprise a differential pressure sensor. The switch is configured to be actuated by the formation of a vacuum to secure the fetal extractor to a fetus. At least partial release of the vacuum releases the switch to stop or pause the timer. The timer may be configured to be reset such that it only records or displays the duration of a specific application of the vacuum device, or it may be configured to record or display a cumulative duration based upon multiple applications of the vacuum device in an absolute sense or during a defined time period. Magnitude as well as the cumulative number of applications of an applied vacuum may also be measured and, optionally, displayed, as may the number of times traction force is applied to an infant during delivery.

摘要： A hand-held fetal vacuum extractor combines a pump and handle into a single hand-held unit. This enables a single operator, such as a doctor, to control vacuum using a vacuum pump, and apply traction to a fetus using a single hand. A handle, having a surface for gripping, is connected to a fetal vacuum cup for being suctioned onto a fetal head. A vacuum pump is connected to the handle and includes an activation surface for activating the vacuum pump. The vacuum pump is fluidly coupled to a the vacuum cup and fetal head. The grip surface of the handle and the activation surface of the pump are in such proximity, during operation, that a single human hand can simultaneously grasp the grip surface and contact the activation surface.

摘要： A device to assist in removing a fetus from a woman's birth canal during childbirth is provided. The device includes a pliable, elongated member having a mouth adapted to fit over the head of a fetus, an insertion wand or applicator for positioning the elongated member over the head of the fetus, and a drawstring attached at the mouth. The elongated member is constructed so that as it is pulled longitudinally from the end opposite the mouth, the elongated member will axially grip the head of the fetus in much the same way that the novelty item, "Chinese handcuffs," grip the finger of a user. Once the elongated member has axially engaged the head of the fetus, the elongated member may be used to extract the fetus from the birth canal.

摘要： A medical device which is manually operable to draw a vacuum using a piston and cylinder combination may be used for creating a vacuum in the cup of a birth extraction device or to withdraw fluids from a body cavity or perform biopsies with a hollow needle. The structure includes a closed loop at the remote end of the cylinder which allows the device to be manipulated by one hand and it may include check valves to prevent any fluid withdrawn from the body from being reinjected into the body cavity or vessel by location of check valves in a withdrawal duct and a drainage port. The same device may be used for injecting fluids into a body cavity and may include structure between the loop and cylinder to apply force to the piston to discharge fluids through a needle attached to the remote end of the cylinder.

摘要： An obstetric suction device for vacuum extractors and consisting of a suction device (11) with a connecting mechanism (15) for a suction hose and a traction device (16) attachable to the cup. The object of the invention is to provide a suction cup which does not give right to any pressure force component, regardless of how the tractive force is applied to the cup. This has been attained by making the traction device (16) in the form of a two-point pulling device which is attachable to two attachments (18) disposed in proximity of the opening (12) of the cup and diametrically opposite to one another.
